Write / Read Reviews

RinnaiNo natural gas? Looking for comfort and convenience when away from home? Don’t worry, tankless propane water heaters are the solution you are looking for.

Tankless heaters powered by propane gas (LPG) can be used for residential water and space heating, when camping, at the cottage, RV-ing, and wherever natural gas and/or electricity is not available (portable models for example). 

Combining the effectiveness of propane and the convenience of tankless water heaters, these devices will offer an amazing quality and versatility. Come and learn more about them!

Efficiency and great performance, that’s what LP offers over natural gas, but not the only advantage you will get. Propane, sometimes makes more sense, is a lot cleaner to the environment, and even easier to use.

When you combine propane and tankless water heaters – the result is even better. Superb performance, convenience, and outstanding results overall – that’s what you get with tankless propane water heaters.

What do tankless propane water heaters offer? Benefits & advantages

Low costs

Despite not being the most affordable fuel option for heaters, propane could be cheaper than electricity and oil. And combining it with the tankless water heater, which provides greater savings over tank-type (over 30%), you will get better savings throughout the year.

Efficiency

As it offers more power than a heat pump and as it is more efficient than natural gas, a propane heater could offer up to 95% of heating efficiency – making it a great option in some regions. When you add the tankless feature, you can save even more propane and reduce costs exponentially while having a longer lifespan.

Environmentally friendly

As well as producing less carbon dioxide, a propane tankless water heater also reduces the carbon footprint and does not contaminate the environment as bad as other. Being one of the cleanest fossil fuels in the market (more than gas and oil), it will help you heat up water more efficiently and without side effects.

Convenience

Easily stored, transported and even reliable due to its liquid state, propane is very convenient to use. Capable of heating up practically anything, it is also incredibly fast to heat (almost twice as fast) as other fuels, and even lasts more due to its efficiency.

Safety

Normally, devices that use LP need to be hundreds of times more resistant and reliable than others. Why? Because propane can travel faster so it becomes a little squishier in devices. And thanks to its safer formula, propane is actually non-harmful when ignited, so you get a totally safe fuel option in every way.

Propane vs. natural gas

Efficiency

Being stored in larger quantities and providing a superior BTU capacity per cubic quantity, propane is almost twice as useful for heating up water. While natural gas offers 1,051 BTU per cubic feet, propane offers up to 2,500 which translates to higher efficiency for heating devices.

Costs

Natural gas is often much more cost-effective solution than propane. The price of propane, on the other side, is cheaper than oil or electricity. The propane heaters are also cheaper to repair than other types.

Environmental impact

Natural gas, when ignited, produces NOx, which is a greenhouse gas that affects the environment. Propane, however, does not do that despite being a similar fuel. Being more efficient and providing more energy per gallon, propane eventually releases much fewer gasses to the atmosphere while producing more energy.

What do tankless heaters offer? Advantages & benefits

Now that you learn some about propane, it is time to know a little more about tankless or on-demand heaters.

Less waste

Not only are tankless heaters more effective in using water, as they hold almost no water and dispose of fewer amounts, the tank-less design and quality of construction also allow tankless heaters to produce less environmental damage when disposed of.

Cleaner water

Without tanks that produce contaminants such as rust and scales – tankless heaters will provide faster and cleaner water directly to your shower or sink. As there is no standing water, it is always fresh.

More water

Don’t need to wait for the heater to warm up the water, simply turn up the device and open the tap, and hot water will immediately come your way (depends on the pipe length and recirculation availability). Even after hours of using, the water is still hot.

More space

Tank heaters occupy too much space in houses. With a tankless heater, you obtain one of the most convenient and space-oriented devices in the market, as they are wall-mounted and as small as the small suitcase.

More efficiency

Without having to save up water and heat it up in the meantime, on-demand water heaters use up to 40% less energy than tank heaters. This is translated into less monthly costs and less wasted energy & water.

Longer lifespan

Almost all tankless heaters not only last longer due to their innovative design, but they also demand less maintenance and have more replaceable parts. This means you have a much more convenient and reliable product.

Why use propane tankless water heaters

Now that you know why tankless heaters are so amazing, and why propane is so effective, it is time to know why tankless water heaters may provide the best results you can think of. Here’s why to use tankless propane water heaters:

  • Propane tankless heaters are more efficient than electric tankless heaters, even natural gas type. Due to the high energy factor, propane models are often found as Energy Star rated models.

  • Propane tankless heaters produce less carbon emissions.

  • Propane tankless heaters may qualify the user for tax credits depending on the use and location.

  • A propane tankless heater does not waste as much energy as a gas tank heater due to higher efficiency.

  • A propane tankless heater will not store water so it won’t waste any energy heating it up.

  • A propane tankless heater is much smaller than a gas tank-type heater.

  • A propane tankless heater can last up to 20 years working, which is up to 10 years more than a tank-type.

  • A propane tankless heater demands less maintenance and care than a conventional type.
